The invention of the computer mouse

A vintage mouse is seen in a display featuring the Xerox Alto personal computer, at the Computer History Museum on January 19, 2011 in Mountain View, Calif.

Originally created in 1964, the computer mouse has evolved through several iterations, from a mechanical device using balls and wheels to optical and laser-guides interfaces, from corded to wireless. But the constantly-changing world of personal devices may one day make these handy tools obsolete.

In 1952 a trackball was developed for the Royal Canadian Navy for use as an interface for the Navy's DATAR (Digital Automated Tracking and Resolving) system, linking computers with communications in a tactical battlefield information system.

The trackball became a key component of a mechanical computer mouse.

Scientist and inventor Douglas Engelbart (1925-2013) directed the Augmentation Research Center lab at Stanford Research Institute (now SRI International), and was a senior scientist at Tymshare and McDonnell Douglas. Engelbart developed such computer innovations as display editing, graphic interfaces, cross-file editing, hypermedia and groupware, but he is best-known as the father of the computer mouse.

Engelbart here shows off the prototype computer mouse, built by SRI's Bill English in 1964 as part of an experiment -- a wood-encased "X-Y Position Indicator For A Display System," as it was called at the time.

"It was no great shakes, the invention," Engelbart said. "It was just putting things together that were already known."

In a December 9, 1968, demonstration (later dubbed "The Mother of All Demos") given by Doug Engelbart and fellow researchers at the Stanford Research Institute (SRI), a view of the future of computing was offered, including the use of a computer mouse, keyboard, and a "keyset" (far left) that could input characters.

Clicking once on the mouse button selected a word on the screen by placing an arrow underneath it; a second click would execute a delete command.

Engelbart explained how a cursor point would track the movements of a mouse made by the computer's operator.

"I don't know why we call it a mouse, sometimes I apologize," Engelbert admitted during the demonstration. "It started that way and we never did change it."

Doug Engelbart won a patent for his mouse in 1970, but he never made a fortune off it. By the time the mouse became commonplace in the late 1980s, his patent's 17-year-life span had expired.

The ball mouse supplied with Alto used light-reading sensors to detect the directional movement of the trackball.

In a review published by the San Francisco Examiner, John Dvorak wrote, "The Macintosh uses an experimental pointing device called a 'mouse'. There is no evidence that people want to use these things."

As tablets (such as the Apple iPad), ebook readers and smartphones became more prevalent, touch-screens became a more common means of interacting with devices than buttons, a stylus, or a mouse.

"We're going to use a pointing device that we're all born with," Jobs said.

At least one billion mice (or is it "mouses"?) have been sold worldwide to date. But with changing technology, the future of the mouse is hardly guaranteed.

In January 2013, mouse-maker Logitech announced it was shifting its business to cater more toward the owners of tablets and smartphones.

That the mouse may eventually fade away would hardly surprise its inventor. "It's hard to believe it won't someday be obsolete," Doug Engelbart once said. "Everybody sort of thinks we're there, and we're just a little ways up a hill. There's *this* much to go."

Engelbart died Tuesday, July 2, 2013, at his California home. He was 88.
